An attitude to life which seeks fulfillment in the single-minded pursuit of wealth -- in short, materialism -- does not fit into this world, because it contains within itself no limiting principle, while the environment in which it is placed is strictly limited.

Call a thing immoral or ugly, soul-destroying or a degradation of man, a peril to the peace of the world or to the well-being of future generations; as long as you have not shown it to be uneconomic you have not really questioned its right to exist, grow, and prosper.

I have no doubt that it is possible to give a new direction to technological development, a direction that shall lead it back to the real needs of man, and that also means: to the actual size of man. Man is small, and, therefore, small is beautiful. To go for giantism is to go for self-destruction.
